allestuetsmerweh / garden.cefpython Goto Github PK

After a while browsing, the application freezes. Not just the browser, also the kivy loop seems blocked. No error / crash.

I can't reproduce the issue yet but it happens from time to time in all applications where this garden.cefpython is used.

system keyboard (physical keyboard) input is being redirected to all focused elements

=> This may be an issue of kivy

command line switch touch-events http://peter.sh/experiments/chromium-command-line-switches/

1. Run tabbed.py
2. create a new tab => google.com gets loaded
3. close all the keyboards
   4.(you can't type into google textinput) & close tab => segfault

when keyboard_mode is systemanddocked and the browser loses focus (another widget is focused), the browser won't un-focus the active HTML element

e.g. selection management does not work in presence of frames (blinking bubble)

-> I dont' know why dis wasn't merged? 2a97fb9

always_block_popups should return False

=> if not multi, when focusing a new widget, the old focus must go away

If CEFPython needs to be downloaded, the popup seems to stay on screen (but is covered by the new content)
Need to find out, how two kivy apps (one after the other) can be used in a correct manner!

When opening a popup, the CEFBrowser widget is given.
This cannot be integrated to a controlled browser created with kv lang.

See here: https://github.com/rentouch/cefkivy/blob/master/cefkivy/browser.py#L328

When I try to run the examples, I'm getting the following error. Please help me out.

from kivy.garden.cefpython import CEFBrowser
ImportError: cannot import name CEFBrowser

• blur, when calling release_keyboard
• re-request keyboard when showing CEFBrowser again in tabbed.py
  => does this even make sense? when resolving the first issue, we don't know the active element for the second issue anymore

If the start-url is about:blank, the back/forward functions won't work properly after loading the first real site.
=> Maybe bug in CEF / CEFPython

Reproduce:

• In examples/controls.py / .kv gets the URL set after the creation of the browser-class => about:blank gets set.
• If you browser the web now, you can't use go_back()

If you change "about:blank" to a url in cefbrowser.py it will work.

CEFBrowser.certificate_error_handler;
TypeError: unbound method must be called with CEFBrowser instance as first argument (got int instance instead)

When Kivy is used with the SDL2 window provider, vkeyboard triggers on_textinput instead of on_key_down.
i don't know if this can be seen as a bug in kivy or not. The commit which introduced this behavior: kivy/kivy@35ca827

When using on_textinput we don't get the modifier keys?
Do we need the modifier keys?

of getBoundingClientRect observer

rather than calling buf.GetString, which probably copies the whole buffer, call buf.GetIntPointer.

Then create a Python MemoryView with PyMemoryView_FromMemory.

Finally, blit that MemoryView into the kivy texture of the widget.

I have to be able to set enable-media-stream on cefpython.Initialize() to be able to use WebRTC features.

As an example I would:
switches = {"enable-media-stream": ""}
cefpython.Initialize(settings, switches)

when i run python3 setup.py install
